Acrivastine

INFORMATION

Uses

Acrivastine is used in the treatment of allergic disorders.

How it works

Acrivastine (also known as propionic acid) belongs to a group of medicines called ‘antihistamines’ that are non-sedative (non-drowsy). Histamine is a natural chemical released in the body that triggers allergic symptoms such as sneezing, runny nose, watery eyes or itching of the skin. Acrivastine blocks the action of histamine thus provides relief from allergic symptoms.

Common side effects

  • Consumption of alcohol should be avoided while on this treatment.
